Abstract

The temporal profile of the small target in the sky background and the disadvantage of traditional method are analyzed. Then we propose a novel method of small target detection based on image sequence in complex sky background. The illumination intensity is normalized firstly in image sequence. Then, the temporal matrix is decomposed using SVD in both horizontal and vertical direction. The small target is extracted in these two directions. Then, add these two images. Finally, segment the image with threshold. Obtain the trajectory of the small target in image sequence. The simulations show that our method is robust and effective.
